Low hue photobleaches

ABSTRACT

Low hue photobleaching compositions comprising organotin (IV), organogermanium (IV), organopaltinum (IV), organopalladium (IV), organolead (IV) or organophosphorous (III) phthalocyanine and napthalocyanines having Q-band absorption maxima at wavelengths greater than 660 nm and increased triplet state yields whereby production of singlet oxygen is increased. Use of Sn 4+ , Ge  4+ , Pt 4+ , Pd 4+ , Pb 4+ , P 3+  pthalocyanine and naphthalocyanines compounds in photobleaching compositions allows for formulation of low hue laundry compositions, bleach compositions, and hard surface cleaners.

FIELD OF THE INVENTION

[0001] The present invention relates to novel organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizing compounds having a Q-band maximum absorption wavelength of 660 nanometers or greater and their use as photoactivators (photosensitizer) or singlet oxygen producers, in particular for low hue photobleaching for removing stains from textiles and hard surfaces. The present invention also relates to laundry compositions and hard surface cleaners comprising the novel organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizing compounds of the present invention. The present invention further relates to a method of delivering compositions comprising low hue photobleaches to soiled and stained fabrics and to hard surfaces.

BACKGROUND OF THE INVENTION

[0002] It is known that certain water-soluble phthalocyanine, naphthalocyanine, and metallocyanine compounds can be used as photobleaching and anti-microbial agents. Phthalocyanines and naphthalocyanines or their metal complexes can form “singlet oxygen” an oxidative species capable of reacting with stains to bleach them to a colorless and usually water-soluble state.

[0003] There are many examples of phthalocyanines and naphthalocyanines photobleaches, the most common being the zinc and aluminum phthalocyanines. In the literature the term “photosensitizer” is often used instead of “photoactivator” and may therefore be considered as standing equally well for the latter term used throughout this specification

[0004] The prior art teaches phthalocyanine and naphthalocyanine compounds having the general structure

[0005] where Me is a transition or non-transition metal, (Sens.) is a phthalocyanine or naphthalocyanine ring which, when combined with a suitable Me unit, is capable of undergoing photosensitization of oxygen molecules, R units are substituent groups which are bonded to the photosensitization ring units (Sens.) to enhance the solubility or photochemical properties of the molecule, and Y units are substituents associated with the metal atom, for example, anions to provide electronic neutrality. The selection of a particular substituent R unit for substitution into the molecule has been the focus of many years of research and these units are typically chosen by the formulator to impart into the target molecule the desired level of water solubility.

[0006] A major limitation to the use of phthalocyanine and naphthalocyanine compounds for fabric photobleaching is the fact that these molecules are highly colored materials.

[0007] A second limitation is that the compounds are not inherently water soluble. It has therefore been the task of phthalocyanine and naphthalocyanine photobleach formulators to provide water soluble photobleaches without adversely affecting their photochemical properties.

[0008] A further task for the formulators of photobleaches has been the need to modify the properties of the photosensitizer (Sens.) unit of the molecule, in other words, to increase the quantum efficiency without reducing the water solubility. While balancing water solubility and enhanced photophysics, the formulator must insure that the structural modifications do not increase the color.

[0009] It is well known to formulators skilled in the art that an R unit which may produce a desired increase in one of these three properties may cause an equally large decrease in one or both of the other desirable properties.

[0010] Surprisingly, it has been found that the compounds of the present invention allow the formulators to modify the levels of solubility, photoefficiency, Q-band wavelength maxima separately without adversely affecting the other parameters of the molecule. This ability to delineate and selectively modify the key structural elements contributing to the target properties of the molecule allows the formulator to proceed without having to rely upon a “hit and miss” stratagem.

[0011] The photobleaches of the invention comprise two “elements”. The photo-sensitizing ring which is optimized for color (hue) and generation of singlet oxygen, and axial groups which are optimized to provide the desired level of solubility, substantivity, and de-aggregation. These two elements will be described in more detail herein below.

[0012] One key to this ability to control the molecular properties is found when contrasting the structure of known photobleaches comprising phthalocyanines and naphthalocyanines with those of the present invention. The examples of photo-bleaches previously described in the art are generally flat molecules due to their planar ring structure. This planarity produces an propensity for these molecules to aggretate wherein this aggregation tends to lead to photochemical quenching, preventing efficient formation of singlet oxygen.

[0013] The organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizing compounds of the present invention comprise axial substituents that act to break up this ordering effect, hence providing an efficiently formed mono-layer of photosensitizers evenly applied to a given substrate. Because each molecule of this mono-layer can now contribute to bleaching there is better cost efficiency to the formulator.

[0014] It has been surprisingly found that because of the separating out of physical properties into “molecular sectors”, e.g. R groups for solubility, new uses for the compounds of the present invention have been realized. Adducts which provide unique solubility profiles, but which detract from the photophysics, were once excluded from use in photobleaches. However, the inclusion of these moieties into the photobleaches of the present invention results in the ability to formulate photobleaches for use in non-classical applications, for example dry cleaning applications. Solvent based or low aqueous solutions of the present invention are now obtainable for the very reason that the present invention provides control over solubility which is manifested in the choice of the axial R substitutions.

[0015] The proper selection of axial R units attached to the compounds of the present invention allow the formulator to balance the changes in photoefficiency of the desired compound with the water solubility of the parent material. In addition, these axial R unit modifications provide the formulator with the ability to balance solubility, Q-band λ_(max), and quantum efficiency of the (Sens.) unit.

[0016] It is an object of the present invention to provide “substantive” and “ non-substantive” organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizers. A “substantive” organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizer will be attracted to a surface and a “non-substantive” organotin, organogermaniumn, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizer will repel a surface.

[0017] It is a further object of the present invention to provide substantive and non-substantive photobleaching laundry compositions for natural, synthetic or blended fabrics.

[0018] It is a further object of the present invention to provide photobleaching compositions that comprise non-aqueous and low aqueous carriers, that is, photobleaching compositions having carriers wherein water constitutes less than half of the carrier liquid.

[0019] It is a further object of the present invention to provide substantive and non-substantive photobleaching hard surface cleaning compositions for non-porous hard surfaces, inter alia, Formica®, ceramic tile, glass, or for porous hard surfaces such as concrete or wood.

[0020] An object of the present invention is to provide a method for bleaching fabric with laundry compositions comprising organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photobleaching compounds of the present invention.

[0021] An object of the present invention is to provide a method for cleaning hard surfaces with compositions comprising organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photobleaching compounds of the present invention.

[0022] An object of the present invention is to provide for low hue organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizing compounds having a Q-band maximum absorption wavelength of at least 660 nanometers.

[0248] When compounds of the present invention have present one or more substituent R¹, R², R³, and R⁴, units, as in the case of phthalocyanine, or R¹, R², R³, R⁴, R⁵, and R⁶ units, as in the case of naphthalocyanines, the exact orientation of the substituents may not be exactly known. However, for the purposes of the compounds of the present invention, certain equivalencies of substitution exist. For example, the two units of the following formula

[0249] which contain the same R¹ substitution, are equivalent for the purposes of the present invention and the selection of either one structure over the other will not effect the desired properties of the molecule described herein.

[0250] In addition, compounds containing the substitution represented by the following formulas

[0251] which contain the same R¹ and R² unit substitutions, are also equivalent for the purposes of the present invention and the selection of either one structure over the other will not effect the desired properties of the molecule described herein. The above examples, however, are only representative of the total number of equivalent structure examples that will be recognized by those skilled in the art.

[0252] Compounds useful for the present invention having substituted one or more R¹, R², R³, and R⁴ unit, as in the case of phthalocyanine, or R¹, R², R³, R⁴, R⁵, and R⁶ unit, as in the case of naphthalocyanines, which have their substitutions oriented in a manner described by the following formula

[0253] are not equivalent for the purposes of the present invention and would each constitute separate compounds regardless of the fact that the R¹ and R² units are equivalent. The above example does not exhaust the number of non-equivalent structures that are possible using any combination of R¹, R², R³, R⁴, R⁵, and R⁶ units recognized by those skilled in the art.

[0254] Solublizing axial R units, are bonded directly to the central tin, germanium, platinum or palladium atom. Each R unit can be chosen independently of the other. The selection of an R unit is made, for example, to provide solubility, non-solubility, “substantivity”, “non-substantivity” to the compound. These are a few examples of the utility of the axial group and those skilled in the art will recognize that other properties of the photobleaches can be controlled via axial substitution. R units are nonionic, cationic, or anionic units.

[0255] Below is an example of a preferred “substantive” embodiment (has an affinity for surfaces, e.g. fabric) of the present invention comprising a phthalocyanine ring system wherein at least one of the R¹, R², R³, and R⁴ units of each aromatic moiety is methoxy, each R group comprises an ethyleneoxy unit of the formula

—(OCH₂CH₂)_(x)Z

[0256] wherein for each R unit Z is methoxy and x is 7.2 thereby giving the moiety an average ethoxylation value of 7.2.

[0257] Below is an example of a “substantive” embodiment (has an affinity for surfaces, e.g. fabric) of the present invention comprising a phthalocyanine ring system wherein at least two of the R¹, R², R³, and R⁴ units of each aromatic moiety is methoxy, each R group comprises an ethyleneoxy unit of the formula

—(OCH₂CH₂)_(x)Z

[0258] wherein for each R unit Z is methoxy and x is 7.2 thereby giving the moiety an average ethoxylation value of 7.2.

[0259] Below is an example of a “non-substantive” embodiment (charged R units reduces the affinity for surfaces, e.g. fabric) of the present invention comprising a naphthalocyanine ring system wherein at least two of the R¹, R², R³, R⁴, R⁵, and R⁶ units of each aromatic moiety are chlorine, one R group comprises an siloxy unit the formula —OSiR⁷R⁸R⁹ wherein R⁷ and R⁸ units are methyl and R⁹ is of the formula

[0260] wherein Z is —SO₃ ⁻M⁺, M is sodium and y is equal to six; the second axial R unit is methoxy.

[0261] Below is an example of a “non-substantive” embodiment (charged R units reduces the affinity for surfaces, e.g. fabric) of the present invention comprising a naphthalocyanine ring system wherein at least one of the R¹, R², R³, R⁴, R⁵, and R⁶ units of each aromatic moiety is bromine, and the R groups comprise an siloxy unit the formula —OSiR⁷R⁸R⁹ wherein R⁷ and R⁸ units are methyl and R⁹ is of the formula

—(CH₂)_(y)Z

[0262] wherein Z is —SO₃ ⁻M⁺, M is sodium and y is equal to six.

[0263] The compounds of the present invention can be modified to have a wide range of surface affinities. Molecules can be made “substantive” or “non-substantive” by the choice of axial R units. The term “substantivity” as defined herein is the property which allows the photobleaching agent to successfully deposit on a targeted surface. For example, the axial groups R, hereinafter defined in the specification, may be selected to provide compatibility of the photobleaching compound with a synthetic fabric, a durable surface such as ceramic tile, or in general any fabric, article of manufacture or situs that is to be a target of photobleaching.

[0267] C) the balance carriers and adjunct materials.

[0268] The present invention further relates to laundry detergent or hard surface cleaning compositions comprising:

[0269] A) at least about 0.1%, preferably from about 0.1% to about 30%, more preferably from about 1% to about 30%, most preferably from about 5% to about 20% by weight, of a detersive surfactant, said detersive surfactant is selected from the group consisting of anionic, cationic, nonionic, zwitterionic, ampholytic surfactants, and mixtures thereof;

[0271] C) the balance carriers and adjunct materials.

[0272] The present invention yet further relates to laundry detergent and hard surface cleaning compositions comprising:

[0273] A) at least about 0.1%, preferably from about 0.1% to about 30%, more preferably from about 1% to about 30%, most preferably from about 5% to about 20% by weight, of a detersive surfactant, said detersive surfactant is selected from the group consisting of anionic, cationic, nonionic, zwitterionic, ampholytic surfactants, and mixtures thereof;

[0274] B) at least about 0.001 ppm, preferably from about 0.01 to about 10000 ppm, more preferably from about 0.1 to about 5000 ppm, most preferably form about 10 to about 1000 ppm, of a photosensitizing compound having a Q-band maximum absorption wavelength of 660 nanometers or greater according to the present invention; wherein selection of a suitable moiety for a R¹, R², R³, R⁴, R⁵, or R⁶ substitutent is capable of providing a positive red shift value of at least 1, preferably a positive red shift value of at least 10, more preferrably a positive red shift value of at least 30, when said moieties are substituted for hydrogen; and

[0275] C) the balance carriers and adjunct materials

[0276] Selection of a specific R moiety is generally made for adjustment of the solubility or substantivity of the molecule. For example, the R unit is matched to the structural properties of either the targeted material (i.e. fabric) or to the targeted substrate (i.e. stain). The option to tailor the properties of the R unit to the material, is due to the ability to select R units independently of effecting the phthalocyanine or naphthalocyanine ring.

[0277] An additional benefit of the photobleaching system of the present invention is that they are generally more fabric and color safe than conventional bleaches (i.e. hypochlorite). “Non-substantive” molecules are desirable for applications where the photosensitizing compound must remain in the liquor rather than becoming attracted to a particular surface, i.e. water sterilization.

[0278] The term “low hue” as used herein and throughout the specification refers to photobleaches that have a λ_(max) of their Q-band above about 700 nm and are therefore only slightly perceptible to the human eye. Those additional materials of the present invention having Q-band maximum wavelengths in the “visible” range, (i.e. 660-700 nanometers) are materials that are most suitable when the perception of a colored material is not a factor in deterring utility.

[0279] Effective photobleaching is predicated on the production of a molecule of singlet oxygen, a theory which has been extensively studied and is well understood by those skilled in the art of photobleaching. Because the singlet oxygen species is short-lived, having the photosensitizing molecule in proximity to the stain or the microbe to be “attacked” is of primary advantage.

[0280] The molecules of the present invention because of the ability of the formulator to control “substantivity”, can be directed to any desired surface. The additional ability to prevent layering and stacking of photosensitizing molecules due to the axial nature of the R units, provides for an efficient mono-layer. For example, an embodiment of the present invention for removing stains from a fabric will have the requirements that the organotin, organogermanium, organoplatinum, organopalladium, organolead, or organophosphorous photosensitizing compound have an affinity for the fabric surface, and that the photobleaching compound be close to the desired site of action. These requirements are achieved by manipulation of one or more R units.

[0281] The present invention also relates to a process for carrying out a photo-sensitized reaction or a reaction catalyzed by singlet oxygen, wherein one or more phthalocyanine or naphthylocyanine compounds in the presence of oxygen, are brought into contact with the medium in which or on which the said reaction is to take place, or are incorporated in this medium, and are irradiated with light.

[0282] It has long been known that phthalocyanine and naphthalocyanine rings, can absorb light quanta and form electronically excited species (singlet and triplet) and that these species can be quenched by oxygen to yield ‘excited oxygen species’. A particularly preferred ‘excited oxygen species’ is singlet oxygen which is most reliably formed by the quenching of the triplet state of a photosensitizer, such as a phthalocyanine, by molecular oxygen. It is therefore an aim of the photobleach formulator to produce compounds that favor the formation of the triplet state.

[0283] When a photosensitizer is irradiated with light, the singlet energy state that results undergoes a variety of processes i.e. re-emission of light (fluorescence). The most important process with regard to photobleaching via singlet oxygen is inter system crossing (ISC). This is the mechanism by which the singlet state is converted to the triplet state. In general, the efficiency of this process is discussed in terms of quantum yield, i.e. the number of photons absorbed that lead to the desired triplet excited state. The present invention provides for increased photobleaching by modifying the efficiency of inter system crossing from the singlet state to the triplet state. The molecules of the present invention, can be modified by the formulator to increase the quantum efficiency of triplet formation via the “heavy atom effect”. The selection of a moiety for its “heavy atom effect” can be made independently of other factors, for example, without undue concern for solubility factors. This is because the choice of axial R groups for solubility will have no bearing on the changes made to the phthalocyanine or naphthalocyanine ring system.

[0284] The determination of the value of the Q-band wavelength and whether a shift occurs in this wavelength when a particular moiety (R¹, R², R³, R⁴, R⁵ or R⁶ unit) replaces a hydrogen atom on the phthalocyanine or naphthalocyanine ring is straight-forward. Typically, a solution having a concentration of approximately 1×10⁻⁶ M of the phthalocyanine or naphthalocyanine to be measured is prepared using a suitable solvent (e.g. dimethylformamide) which contains 1 wt % triton X-100. A UV/visible spectrum is then obtained and the Q-band λ_(max) is recorded. This value is the “substrate λ_(s-max)”. A spectrum for the material prior to introduction of the substituent group is obtained in the same manner. This value is the “reference λ_(r-max)”. The two spectra are compared and the resulting measured values are placed into the following equation

wavelength red shift=Δλ_(max)=λ_(s-max)−λ_(r-max)

[0285] wherein if the number obtained is greater than or equal to 1, then the substituent group has produced a positive red shift of at least one nanometer and the substituent is a preferred embodiments of the present invention. If the material of interest is not soluble in dimethylformamide another suitable solvent may be used.

[0287] For the purposes of the present invention the delta triplet yield is determined by determining the % quantum yield of triplet fro the phthalocyanine or naphthalocyanine of interest and this is the term Φ_(trip-substrate). The % quantum yield of triplet for the phthalocyanine or naphthalocyanine prior to introduction of the substituent is determine. This value is Φ_(trip-reference). The value are place in the following equation

triplet state quantum yield increase=ΔΦ_(trip)=Φ_(trip-substrate)−Φ_(trip-reference)

[0288] When the value for ΔΦ_(trip) is a number greater than or equal to 1, the substitution made therein for a hydrogen atom on the (Sens.) unit of the photosensitizer is a preferred embodiments of the present invention.

[0289] In particular, the present invention relates to process for bleaching or removing stains from textiles, organic or inorganic substrates. It is further an object of the present invention to protect the latter against attack by microorganisms, wherein the substrates are treated with phthalocyanines or naphthalocyanies of the present invention, in the presence of water and while being irradiated by light.

[0290] Another advantage of the present invention is the fact that each R unit may be directed toward a separate desired property and the molecules of the present invention can therefore be thought of as being “sided”. For example, one axial R unit may be direct toward increased solubility while the other axial R group may be chosen for its ability to provide increase substantivity.

[0291] The present invention also relates to a process for carrying out a photo-sensitized reaction or a reaction catalyzed by singlet oxygen, wherein one or more phthalocyanine or naphthylocyanine compounds in the presence of oxygen, are brought into contact with the medium in which or on which the said reaction is to take place, or are incorporated in this medium, and are irradiated with light.

[0292] If the method is carried out in an aqueous medium (for example the sterilization of textiles), the irradiation with light can either be carried out directly in the treatment medium by means of an artificial source of light mounted inside or outside the medium or the substrates, in a moist state, can subsequently either be irradiated, again by means of an artificial source of light, or can be exposed to sunlight. Good antimicrobial effects of the present compounds can be achieved even with very low concentrations of active substance, for example at 0.001 ppm. Depending on the field of use and on the phthalocyanine or naphthylocyanine derivative employed, a concentration between 0.005 and 100, preferably 0.01 and 50 ppm is preferable. The irradiation can be effected by means of an artificial source of light or by means of sunlight. The intensity of the illumination can vary within wide limits, and it depends both on the concentration of active as well as the nature of the light source as to the photobleaching efficiency of any particular compound of the present invention. A further parameter which can be varied is the exposure time, i.e. for the same effect exposure must be longer at a lower light intensity than at a higher intensity. In general, depending on the field of use, exposure time of a few minutes up to a few hours is possible.

[0293] If the process is carried out in an aqueous medium (for example the sterilization of textiles), the irradiation with light can either be carried out directly in the treatment medium, by means of an artificial source of light mounted inside or outside the medium, or the articles, in a moist state, can subsequently either be irradiated, again by means of an artificial source of light, or can be exposed to sunlight. Good antimicrobial effects con be achieved even with very low concentrations of active substance, for example at 0.001 ppm. Depending on the field of use and on the phthalocyanine or naphthylocyanine derivative employed, a concentration between 0.005 and 2000, preferably 0.01 and 1000 ppm is preferable.

[0294] The methods of the present invention can also be accomplished in solvent based carriers or in low aqueous solutions. For the purpose of the present invention the term low aqueous means that water is added to a carrier system to modify the properties of the carrier and not solely for the purpose of solublizing the substrate. For example, solvents that are capable of holding solublized oxygen as well as forming a miscible system with water are preferred. Non-limiting examples of these solvents are butoxy propoxy propanol (BPP), methoxy propoxy propanol (MPP), ethoxy propoxy propanol (EPP), and propoxy propoxy propanol (PPP). Embodiments of the present invention which comprise these non-classical aqueous compositions are most useful when the photobleach must be applied to a woven fabric or surface that contains agents which repel water and moisture.

[0295] The sterilization of textiles of synthetic or natural original may be mentioned as an important application. Thus, material to be washed in the household or in industry can be disinfected by means of the methods of the present invention. The material to be washed can be treated for this purpose in the manner mentioned above with aqueous solutions of the phthalocyanines or naphthalocyanines of the present invention while being irradiated with light. The phthalocyanine and naphthalocyanines can advantageously be present in the treatment medium in a concentration of from 0.01 to about 2000 mg per liter, preferably from 0.1 to 1000, more preferably from 1 to 500. The sterilization can be carried out advantageously together with the washing process. For this purpose, the material to be washed is treated with a wash medium containing customary detergent substances, one or more phthalocyanines or naphthalocyanines according to the present invention and, if desired, inorganic salts and/or other adjunct materials having antimicrobial properties. The washing process con be carried out manually, for example in a tub, or can be carried out in a washing machine. The necessary exposure to light can be effected during the washing process by means of suitable light sources, or the moist material being washed can also, subsequently, for example during drying , either be exposed to a suitable artificial source of light or simply exposed to sunlight, for example line drying.

[0296] Surface bleaching can be achieved, for example by applying to the appropriate surface, an aqueous solution of the phthalocyanine or naphthalocyanine compound according to the present invention, this solution preferably comprising from about 0.001 to about 10%, by weight of active substance. The solution can also comprise, in addition, other customary additives, for example wetting agents, dispersing agents or emulsifiers, detergent substances and, if desired inorganic salts. After this solution has been applied, the surface is simply exposed to sunlight or, if required, it can in addition be irradiated by means of an artificial source of light. It is advisable to keep the surface moist during the exposure to light.

[0297] The laundry compositions of the present invention optionally comprise detersive surfactants, examples of which are, anionic, cationic, nonionic, amphoteric and zwitterionic, however the formulator is not limited to these examples or combinations thereof. The surfactants are present from about 0% to about 95%, preferably from about 5% to about 30%, by weight of the composition.

[0298] The cleaning compositions of the present invention optionally comprise detersive surfactants, examples of which are, anionic, cationic, nonionic, amphoteric and zwitterionic, however the formulator is not limited to these examples or combinations thereof. The surfactants are present from about 0% to about 50%, preferably from about 5% to about 30%, by weight of the composition.

[0299] The laundry compositions of the present invention optionally contains builders, examples of which are, silicates, carbonates, and zeolites, however the user is not limited to these examples or combinations thereof. The builders are present from about 0% to about 50%, preferably from about 5% to about 30%, by weight of the composition.

[0300] The cleaning compositions of the present invention optionally contains builders, examples of which are, silicates, carbonates, and zeolites, however the user is not limited to these examples or combinations thereof. The builders are present from about 0% to about 50%, preferably from about 5% to about 30%, by weight of the composition.

[0301] The hard surface cleaner of the present invention optionally contains builders, examples of which are, silicates, carbonates, and zeolites, however the user is not limited to these examples or combinations thereof. The builders are present from about 0% to about 50%, preferably from about 5% to about 30%, by weight of the composition.

[0302] The hard surface cleaner of the present invention optionally contains abrasives from about 0.5% to about 85%, preferably from about 10% to about 85%, by weight of the composition. Suitable abrasives are silicates, carbonates, perlite, clay, and pulverized ceramic clay, however, the user is not restricted to these examples or combinations thereof.

[0303] Substances which increase the action can also be added in the process according to the invention, inter alia electrolytes, for example inorganic salts, for instance sodium chloride, potassium chloride, sodium sulfate, potassium sulfate, sodium acetate ammonium acetate, alkali metal phosphates and alkali metal tri-polyphosphates, especially sodium chloride and sodium sulfate. These salts can be added to the agents according to the invention or can be added directly in the application method, so that they are present in the application solution in a concentration of, preferably 0.1 to 10%, by weight.

[0304] What is meant by the term aqueous solution is a solution that is essentially water, however the formulator may include adjunct materials as well as a surfactant to aid in removal of the “treated” micro organisms during rinsing or subsequent cleaning. The presence of an aqueous solution facilitates the production of singlet oxygen due to the higher concentration of oxygen in water than in air.

[0305] Surfactant—The instant cleaning compositions contain from about 0.1% to about 60% by weight of a surfactant selected from the group consisting of anionic, nonionic, ampholytic and zwitterinonic surface active agents. For liquid systems, surfactant is preferably present to the extent of from about 0.1% to 20% by weight of the composition. For solid (i.e. granular) and viscous semi-solid (i.e. gelatinous, pastes, etc.) systems, surfactant is preferably present to the extent of from about 1.5% to 30% by weight of the composition.

[0306] Nonlimiting examples of surfactants useful herein typically at levels from about 1% to about 55%, by weight, include the conventional C₁₁-C₁₈ alkyl benzene sulfonates (“LAS”) and primary, branched-chain and random C₁₀-C₂₀ alkyl sulfates (“AS”), the C₁₀-C₈ secondary (2,3) alkyl sulfates of the formula CH₃(CH₂)_(x)(CHOSO₃ ⁻M⁺) CH₃ and CH₃ (CH₂)_(y)(CHOSO₃ ⁻M⁺) CH₂CH₃ where x and (y+1) are integers of at least about 7, preferably at least about 9, and M is a water-solubilizing cation, especially sodium, unsaturated sulfates such as oleyl sulfate, the C₁₀-C₁₈ alkyl alkoxy sulfates (“AE_(x)S”; especially EO 1-7 ethoxy sulfates), C₁₀-C₁₈ alkyl alkoxy carboxylates (especially the EO 1-5 ethoxycarboxylates), the C₁₀-C₁₈ glycerol ethers, the C₁₀-C₁₈ alkyl polyglycosides and their corresponding sulfated polyglycosides, and C₁₂-C₁₈ alpha-sulfonated fatty acid esters. If desired, the conventional nonionic and amphoteric surfactants such as the C₁₂-C₁₈ alkyl ethoxylates (“AE”) including the so-called narrow peaked alkyl ethoxylates and C₆-C₁₂ alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), C₁₂-C₁₈ betaines and sulfobetaines (“sultaines”), C₁₀-C₁₈ amine oxides, and the like, can also be included in the overall compositions. The C₁₀-C₁₈ N-alkyl polyhydroxy fatty acid amides can also be used. Typical exanples include the C₁₂-C₁₈ N-methylglucamides. See WO 9,206,154. Other sugar-derived surfactants include the N-alkoxy polyhydroxy fatty acid amides, such as C₁₀-C₁ ₁₈ N—(3-methoxypropyl) glucamide. The N-propyl through N-hexyl C₁₂-C₁₈ glucamides can be used for low sudsing. C₁₀-C₂₀ conventional soaps may also be used. If high sudsing is desired, the branched-chain C₁₀-C₁₆ soaps may be used. Mixtures of anionic and nonionic surfactants are especially useful. Other conventional useful surfactants are described further herein and are listed in standard texts.

[0307] Anionic surfactants can be broadly described as the water-soluble salts, particularly the alkali metal salts, of organic sulfuric reaction products having in their molecular structure an alkyl radical containing from about 8 to about 22 carbon atoms and a radical selected from the group consisting of sulfonic acid and sulfuric acid ester radicals. (Included in the term alkyl is the alkyl portion of higher acyl radicals.) Important examples of the anionic synthetic detergents which can form the surfactant component of the compositions of the present invention are the sodium or potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols (C₈-18 carbon atoms) produced by reducing the glycerides of tallow or coconut oil; sodium or potassium alkyl benzene sulfonates, in which the alkyl group contains from about 9 to about 15 carbon atoms, (the alkyl radical can be a straight or branched aliphatic chain); sodium alkyl glyceryl ether sulfonates, especially those ethers of the higher alcohols derived from tallow and coconut oil; sodium coconut oil fatty acid monoglyceride sulfates and sulfonates; sodium or potassium salts of sulfuric acid ester of the reaction product of one mole of a higher fatty alcohol (e.g. tallow or coconut alcohols) and about 1 to about 10 moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfates with about 1 to about 10 units of ethylene oxide per molecule and in which the alkyl radicals contain from 8 to 12 carbon atoms; the reaction products of fatty acids are derived from coconut oil sodium or potassium salts of tatty acid amides of a methyl tauride in which the fatty acids, for example, are derived from coconut oil and sodium or potassium beta-acetoxy- or beta-acetamido-alkanesulfonates where the alkane has from 8 to 22 carbon atoms.

[0308] Additionally, secondary alkyl sulfates may be used by the formulator exclusively or in conjunction with other surfactant materials and the following identifies and illustrates the differences between sulfated surfactants and otherwise conventional alkyl sulfate surfactants. Non-limiting examples of such ingredients are as follows.

[0309] Conventional primary alkyl sulfates (LAS), such as those illustrated above, have the general formula ROSO3−M+ wherein R is typically a linear C8-22 hydrocarbyl group and M is a water solublizing cation, for example sodium LAS. Branched chain primary alkyl sulfate surfactants (i.e., branched-chain “PAS”) having 8-20 carbon atoms are also know; see, for example, Eur. Pat. Appl. 439,316, Smith et al., filed Jan. 21, 1991.

[0310] Conventional secondary alkyl sulfate surfactants are those materials which have the sulfate moiety distributed randomly along the hydrocarbyl “backbone” of the molecule. Such materials may be depicted by the structure

CH₃(CH₂)_(n)(CHOSO₃ ⁻M⁺)(CH₂)_(m)CH₃

[0311] wherein m and n are integers of 2 of greater and the sum of m+n is typically about 9 to 17, and M is a water-solublizing cation.

[0312] The aforementioned secondary alkyl sulfates are those prepared by the addition of H₂SO₄ to olefins. A typical synthesis using alpha olefins and sulfuric acid is disclosed in U.S. Pat. No. 3,234,258, Morris, issued Feb. 8, 1966 or in U.S. Pat. No. 5,075,041, Lutz, issued Dec. 24, 1991. The synthesis conducted in solvents which afford the secondary (2,3) alkyl sulfates on cooling, yields products which, when purified to remove the unreacted materials, randomly sulfated materials, unsulfated by-products such as C10 and higher alcohols, secondary olefin sulfonates, and the like, are typically 90+% pure mixtures of 2- and 3- sulfated materials (some sodium sulfate may be present) and are white, non tacky, apparently crystalline, solids. Some 2,3-disulfates may also be present, but generally comprise no more than 5% of the mixture of secondary (2,3) alkyl mono-sulfates. Such materials are available as under the name “DAN”, e.g., “DAN 200” from Shell Oil Company.

[0313] Bleaching Agents and Bleach Activators—The detergent compositions herein may optionally contain bleaching agents or bleaching compositions containing a bleaching agent and one or more bleach activators. When present, bleaching agents will typically be at levels of from about 1% to about 30%, more typically from about 5% to about 20%, of the detergent composition, especially for fabric laundering. If present, the amount of bleach activators will typically be from about 0.1% to about 60%, more typically from about 0.5% to about 40% of the bleaching composition comprising the bleaching agent-plus-bleach activator.

[0314] The bleaching agents used herein can be any of the bleaching agents useful for detergent compositions in textile cleaning, hard surface cleaning, or other cleaning purposes that are now known or become known. These include oxygen bleaches other than the hypohalite (e.g. hypochlorite) bleaches. Perborate (e.g., mono- or tetra-hydrate sodium salts) and percarbonate bleaches can be used herein.

[0315] Another category of bleaching agent that can be used without restriction encompasses percarboxylic acid bleaching agents and salts thereof. Suitable examples of this class of agents include magnesium monoperoxyphthalate hexahydrate, the magnesium salt of metachloro perbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid and diperoxydodecanedioic acid. Such bleaching agents are disclosed in U.S. Pat. No. 4,483,781, Hartman, issued Nov. 20, 1984, U.S. patent application Ser. No. 740,446, Burns et al, filed Jun. 3, 1985, European Patent Application 0,133,354, Banks et al, published Feb. 20, 1985, and U.S. Pat. No. 4,412,934. Chung et al, issued Nov. 1, 1983. Highly preferred bleaching agents also include 6nonylamino-6-oxoperoxycaproic acid as described in U.S. Pat. No. 4,634,551, issued Jan. 6, 1987 to Burns et al.

Suitable peroxygen bleaching compounds include sodium carbonate peroxn hydrate and equivalent “percarbonate” bleaches, sodium pyrophosphate peroxyhydrate. urea peroxyhydrate, and sodium peroxide. Persulfate bleach (e.g., OXONE, manufactured commercially by DuPont) can also be used.

[0317] A preferred percarbonate bleach comprises dry particles having an average particle size in the range from about 500 micrometers to about 1,000 micrometers, not more than about 10% by weight of said particles being smaller than about 200 micrometers and not more than about 10% by weight of said particles being larger than about 1,250 micrometers. Optionally, the percarbonate can be coated with silicate, borate or water-soluble surfactants. Percarbonate is available from various commercial sources such as FMC, Solvay and Tokai Denka.

[0318] Mixtures of bleaching agents can also be used.

[0319] Peroxygen bleaching agents, the perborates, the percarbonates, etc., are preferably combined with bleach activators, which lead to the in situ production in aqueous solution (i.e., during the washing process) of the peroxy acid corresponding to the bleach activator. Various nonlimiting examples of activators are disclosed in U.S. Pat. No. 4,915,854, issued Apr. 10, 1990 to Mao et al, and U.S. Pat. No. 4,412,934. The nonanoyloxybenzene sulfonate (NOBS) and tetraacetyl ethylene diamine (TAED) activators are typical, and mixtures thereof can also be used. See also U.S. Pat. No. 4,634,551 for other typical bleaches and activators useful herein.

[0320] Highly preferred amido-derived bleach activators are those of the formulae:

R¹N(R⁵)C(O)R²C(O)L or R¹C(O)N(R⁵)R²C(O)L

[0321] wherein R¹ is an alkyl group containing from about 6 to about 12 carbon atoms, R² is an alkylene containing from 1 to about 6 carbon atoms, R⁵ is H or alkyl, aryl, or alkaryl containing from about 1 to about 10 carbon atoms, and L is any suitable leaving group. A leaving group is any group that is displaced from the bleach activator as a consequence of the nucleophilic attack on the bleach activator by the perhydrolysis anion. A preferred leaving group is phenyl sulfonate.

[0322] Preferred examples of bleach activators of the above formulae include (6-octanamido-caproyl)oxybenzenesulfonate, (6-nonanamidocaproyl)oxybenzenesulfonate, (6-decanamido-caproyl)oxybenzenesulfonate, and mixtures thereof as described in U.S. Pat. No. 4,634,551, incorporated herein by reference.

[0323] Another class of bleach activators comprises the benzoxazin-type activators disclosed by Hodge et al in U.S. Pat. No. 4,966,723, issued Oct. 30, 1990, incorporated herein by reference. A highly preferred activator of the benzoxazin-type is:

[0324] Still another class of preferred bleach activators includes the acyl lactam activators, especially acyl caprolactams and acyl valerolactams of the formulae:

[0325] wherein R⁶ is H or an alkyl, aryl, alkoxyaryl, or alkaryl group containing from 1 to about 12 carbon atoms.

See also U.S. Pat. No. 4,545,784, issued to Sanderson, Oct. 8, 1985, incorporated herein by reference, which discloses acyl caprolactams, including benzoyl caprolactam, adsorbed into sodium perborate.

[0326] As a practical matter, and not by way of limitation, the compositions and processes herein can be adjusted to provide on the order of at least one part per ten million of the active bleach catalyst species in the aqueous washing liquor, and will preferably provide from about 0.1 ppm to about 700 ppm, more preferably from about 1 ppm to about 500 ppm, of the catalyst species in the laundry liquor.

[0327] Bleaching agents other than oxygen bleaching agents are also known in the art and can be utilized herein. One type of non-oxygen bleaching agent of particular interest includes photoactivated bleaching agents such as the sulfonated zinc and/or aluminum phthalocyanines. See U.S. Pat. No. 4,033,718, issued Jul. 5, 1977 to Holcombe et al. If used, detergent compositions will typically contain from about 0.025% to about 1.25%, by weight, of such bleaches, especially sulfonate zinc phthalocyanine.

[0328] Buffers—Buffers can be included in the formulations herein for a variety of purposes. One such purpose is to adjust the cleaning surface pH to optimize the hard surface cleaner composition effectiveness relative to a particular type of soil or stain. Buffers may be included to stabilize the adjunct ingredients with respect to extended shelf life or for the purpose of maintaining compatibility between various aesthetic ingredients. The hard surface cleaner of the present invention optionally contains buffers to adjust the pH in a range from about 7 to about 13, preferably from about 8 to about 13, more preferably from about 10 to about 11. Non-limiting examples of such suitable buffers are potassium carbonate, sodium carbonate, and sodium bicarbonate, however, the formulator is not restricted to these examples or combinations thereof.

ADJUNCT MATERIALS

[0329] The compositions herein can optionally include one or more other detergent adjunct materials or other materials for assisting or enhancing cleaning performance, treatment of the surface to be cleaned, or to modify the aesthetics of the composition (e.g., perfumes, colorants, dyes, etc.). The following are illustrative examples of such adjunct materials but are not meant to be exclusive or limiting in scope.

[0330] Chelating Agents—The detergent compositions herein may also optionally contain one or more iron and/or manganese chelating agents. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates.

[0331] Amino carboxylates useful as optional chelating agents include ethylenediaminetetracetates, N-hydroxyethylethylenediaminetriacetates, nitrilotriacetates, ethylenediamine tetraproprionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldiglycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein.

[0332] Amino phosphonates are also suitable for use as chelating agents in the compositions of the invention when at lease low levels of total phosphorus are permitted in detergent compositions, and include ethylenediaminetetrakis (methylenephosphonates) as DEQUEST. Preferred, these amino phosphonates to not contain alkyl or alkenyl groups with more than about 6 carbon atoms.

[0333] Polyfunctionally-substituted aromatic chelating agents are also useful in the compositions herein. See U.S. Pat. No. 3,812,044, issued May 21, 1974, to Connor et al. Preferred compounds of this type in acid form are dihydroxydisulfobenzenes such as 1,2-dihydroxy-3,5-disulfobenzene.

[0334] A preferred biodegradable chelator for use herein is ethylenediamine disuccinate (“EDDS”), especially the [S,S] isomer as described in U.S. Pat. No. 4,704,233, Nov. 3, 1987, to Hartman and Perkins.

[0335] If utilized, these chelating agents will generally comprise from about 0.1% to about 10% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.1% to about 3.0% by weight of such compositions

[0336] Inert Salts. The inert salts (filler salts) used in the compositions of the present invention can be any water-soluble inorganic or organic salt or mixtures of such salts which do not destabilize the surfactant. For the purposed of the present invention, “water-soluble” means having a solubility in water of at least 1 gram per 100 grams of water at 20° C. Examples of suitable salts include various alkali metal and/or alkali earth metal sulfate, chlorides, borates, bromides, fluorides, phosphates, carbonates, bicarbonates, citrates, acetates, lactates, etc.

[0337] Specific examples of suitable salts include sodium sulfate, sodium chloride, potassium chloride, sodium carbonate, potassium sulfate, lithium chloride, lithium sulfate, tripotassium phosphate, sodium borate, potassium bromide, potassium fluoride, sodium bicarbonate, magnesium sulfate, magnesium chloride, sodium citrate, sodium acetate, magnesium lactate, sodium fluoride.

[0338] Abrasives. An essential component of many solid or viscous semi-solid hard surface cleaning compositions is the abrasive material added to facilitate the action of scouring. Abrasive scouring cleansers provide a convenient and useful means for carrying out the sanitizing of porcelain and tile surfaces, especially tubs, showers and toilet bowls. The particulate abrasive material within such compositions serves to abrade and loosen soil adhering to hard surfaces and further serves to create more intimate contact between hard surface stain and the surfactant and/or bleaching agents also present in the cleansing compositions.

[0339] Abrasive cleaners have traditionally contained water-insoluble, relatively hard, particulate mineral material as the abrasive agent. The most common such abrasive agent is finely divided silica sand having particle size varying between about 1 and 300 microns and specific gravity of about 2.1 or higher. While such material is generally very effective in scouring soil and stains from the surfaces being treated, abrasive material of this type tends to be difficult to rinse away from the toilet bowl, shower or bathtub surface.

[0340] In the case where moderate or highly water soluble abrasive material is required (i.e. sodium carbonate) imidodisulfate can be used as the sole abrasive or otherwise added in part.

[0341] It has been discovered that abrasive compositions of this desired type can be realized by utilizing a particular type of expanded perlite abrasive in combination with the surfactants, filler material, and other optional scouring material ingredients listed herein. The abrasive materials suitable to the present invention are those contained in U.S. Pat. No. 4,051,056, Hartman, issued Sep. 27, 1977 and included herein by reference.

[0342] Perfumes. Perfumes are an important ingredient especially for the liquid composition embodiment. Perfume is usually used at levels of from 0% to 5%. In U.S. Pat. No. 4,246,129, Kacher, issued Jan. 20, 1981 (incorporated herein by reference), certain perfume materials are disclosed which perform the added function reducing the solubility of anionic sulfonate and sulfate surfactants.

[0343] Dyes. Dyes may be include at levels of from abut 0.5% to 12%, preferably 1.5% to 5%. Solids and viscous semi-solids can be made with 1.5% dye and no perfume. Examples of suitable dyes are Alizarine Light Blue B (C.I. 63010), Carta Blue VP (C.I. 24401), Acid Green 2G (C.I. 42085), Astrogen Green D (C.I. 42040), Supranol Cyanine 7B (C.I. 42675, Maxilon Blue 3RL (C.I. Basic Blue 80), Drimarine Blue Z-RL (C.I. Reactive Blue 18), Alizarine Light Blue H-RL (C.I. Acid Blue 182), FD&C Blue No. 1 and FD&C Green No. 3. (See the patents of Kitko, U.S. Pat. No. 4,248,827 issued Feb. 3, 1981 and U.S. Pat. No. 4,200,606, issued Apr. 29, 1980, both incorporated herein by reference.) C.I. refers to Color Index.

[0344] Optional Adjuncts Ingredients. As a preferred embodiment, the conventional adjunct ingredients employed herein can be selected from typical components such as enzymes (compatible with the applicable with other adjunct ingredients), especially proteases, lipases, cellulases, color speckles, suds boosters, suds supressors, anti-tarnish and/or anti-corrosion agents, soil-suspending agents, germicides, alkalinity sources, hydrotropes, anti-oxidants, enzyme stabilizing agents, solvents, clay soil chelating agents will generally comprise from about 0.1% to about 10% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.1% to about 3.0% by weight of such composition removal/anti-redeposition agents, polymeric dispersing agents, dye transfer inhibiting agents, including polyamine N-oxides such as polyvinylpyrrolidone and copolymers of N-vinyl imidazole and N-vinyl pyrrolidone, etc.
